Marinate the shrimp. Combine all ingredients for the marinade in a large zip-top bag, then add your shrimp. Seal the bag, removing any excess air, then marinate in the refrigerator for 30-60 minutes.
Preheat the skillet. Preheat a large cast iron skillet or pan over medium-high heat on your grill or stovetop.
Season onions and peppers. Toss your onions and peppers in avocado oil to thoroughly coat, then season with fajita seasoning, or Hey Grill Hey Fiesta Rub.
Prep the toppings. Assemble all of your fajita toppings so you are ready to eat just as the food finishes cooking.
Cook the shrimp. Add 1 Tablespoon avocado oil to the preheated skillet. Remove the shrimp from the marinade and then add to the skillet. Cook for 3-4 minutes per side, or until the shrimp reads 140 degrees F internal temperature. Remove the shrimp to a bowl and let rest.
Cook the vegetables. Add the seasoned vegetables to the hot skillet and cook for 4-5 minutes, stirring occasionally. Turn off the heat on the skillet.
Assemble and serve. Return the shrimp to the hot skillet with the vegetables and serve to your family for a restaurant-style sizzling finish. Serve with warmed tortillas and all of your favorite fajita toppings.
